4.2 Transmitting Power and Receiving Sensitivity
4.2.1 Transmitting Power
Transmitting power is an important indicator of the module performance. Table 4-2 shows the maximum
working power of WM620 and the corresponding 3GPP standards.

4.2.2 Receiving Sensitivity
Receiving sensitivity is another important performance indicator of the wireless modules. It measures the
module's capability to receive weak signals. Table 4-3 lists WM620 data obtained in lab tests for different
bands and corresponding 3GPP standards.
